South Korea's total supply in manufacturing gained ground in the April-June period marking five straight quarters of growth on a sharp rise in imports, but the pace slowed down slightly, government data showed Tuesday.

The manufacturing domestic supply index that measures both goods produced locally and brought into the country, advanced 5.3 percent on-year to stand at 116.9, according to the data compiled by Statistics Korea.

The on-year growth slowed down from a record 7.2-percent gain tallied three months earlier as the solid rise in imported goods supply was offset by a weak increase in domestic supply.
